Description
Technical field
This utility model belongs to Machining Technology field, is specifically related to a kind of shear test frock.
Background technology
In existing product, part, need to measure shearing strength, such as sunk screw, bolt etc., be referred to as testpieces.?
When testpieces is carried out shearing test, inevitably need to use to realize the company between puller system and testpieces to frock
Connect.New patent as real in the China of Application No. 201420716282.0 discloses " a kind of bolt shearing test clamp ", including dividing
Connector and plate face that body is arranged extend perpendicularly to the shear plate of left and right directions, connector is provided with for testing machine
The testing machine attachment structure being connected, bolt shearing test clamp also includes for shear plate is connected to described connection in use
Shear plate attachment structure on part, the confession that shear plate offers at least one axis bearing of trend in left-right direction is waited to try accordingly
Test the bolt penetration hole that bolt installs.But this device there will be problem below in use: 1, due to shear plate and connection
Between part with bolts, it is during shearing test, insufficient strength, easily occur fracture, and when bolt occur
During bending, its stress changes, the shearing strength tested out can be inaccurate；2, the bolt by two shear plates is needed to wear when mounted
Hole is directed at, and is then inserted into bolt to be tested, very inconvenient；3, when needing the shearing strength testing single bolt, due to
Bolt the most to be tested between two shear plates, the structure the most not positioned, unstable situation easily occurs.
Utility model content
This utility model is intended to provide a kind of shear test frock, installs inconvenience, intensity solving present test tool
Low, unstable problem.
A kind of shear test frock in this programme, including upper cutter, lower cutter and limit assembly, described upper cutter and under
Cutting knife is all formed in one, and described upper cutter is provided with two instrument connections side by side along its length, and described upper cutter is in test
Hole be provided around multiple installing hole, described limit assembly is provided with multiple through hole, the installing hole of described limit assembly with on cut
The through hole one_to_one corresponding of cutter, is equipped with fixing bolt and connects fixing to limit assembly and upper cutter in corresponding installing hole and through hole
Connecing, limit assembly is provided with the opening inserted for lower cutter, and described lower cutter is provided with the circular hole aligned with instrument connection,
Testpieces is arranged in the instrument connection and circular hole aligned, and described limit assembly is provided with the opening passed for testpieces.
Operation principle of the present utility model: upper cutter and lower cutter all use the structure of a bodily form type, improve its intensity,
When testing testpieces, its stress influence is less, and the shearing strength therefore tested out is more accurate.During operation, peace
Dress hole and through hole can be adjusted according to actual needs, and its number is increased or decreased, and fixing bolt is relative through position
Through hole and installing hole, be fixedly mounted on limit assembly on upper cutter, and the opening on limit assembly inserts for lower cutter.By
Being provided with instrument connection in upper cutter, lower cutter is provided with circular hole, instrument connection and circular hole and aligns, by testpieces through instrument connection and
The opening passed for testpieces is had on circular hole, and limit assembly.The design of two instrument connections, can test two simultaneously
Testpieces, it is possible to test single test part is more practical.By testpieces through opening, after being placed in instrument connection and circular hole, will
Upper and lower cutting knife is separately fixed at puller system top and bottom, starts puller system, respectively upper cutter and lower cutter is imposed phase negative side
To pulling force, testpieces can be carried out shearing test, determine its shearing strength.
The beneficial effects of the utility model: mainly have three advantages in this programme: one, upper cutter and lower cutter all use one
The structure of bodily form type, improves its intensity, and when testing testpieces, its stress influence is less, therefore tests out
Shearing strength is more accurate.Two, easy for installation, lower cutter only need to insert in limit assembly, it is not necessary to alignment correction repeatedly,
Simple to operate.Three, lower cutter is in inserting limit assembly, and after having installed testpieces, the surrounding of limit assembly can be to test
Part plays the effect blocking its skew, improves its stability, and test data are more accurate, due to the raising of testpieces stability, no
Its skew can be caused to skid off, and therefore operating also can be safer.
Further, the portal structures that described limit assembly is formed in one, such be advantageous in that very convenient, use
Time, the through-hole alignment installing hole on the limit assembly of portal structures only can need to be fixed installation, then by lower cutter from
The side that limit assembly is opened is inserted, and the structure of door shape also has enough space openings and passes in order to testpieces.
Further, described limit assembly includes two sections of backing plates and two block pressur plates, and described backing plate is positioned over upper cutter and pressing plate
Between, two sections of described backing plates are vertically-mounted and have gap, and described lower cutter inserts between backing plate from gap location, described pressing plate water
Safety is loaded on above backing plate and spaced, and described backing plate and pressing plate form ring-shaped, and the center is for pass for testpieces
Opening, the through hole on described backing plate and pressing plate has two or more respectively.Above-mentioned design is advantageous in that, use four independent
Installed part forms limit assembly by cooperation, and each single backing plate and pressing plate can individually be processed, such as portal structures
Limit assembly for, processing is got up convenient, and pressing plate is arranged on backing plate, permissible.
Further, described pressing plate is provided with hole, location, is installed with bolt in the hole, location above lower cutter.Work as incision
When cutter inserts the space between backing plate, only need to up slide, by the position in hole, regulation location, lower cutter can be allowed to arrive to location
After bolt, the circular hole on lower cutter just aligns with the instrument connection of upper cutter, so installs the most simple and convenient.
